Content distribution system, content distribution server, content distribution method, software program, and storage medium

摘要

A content distribution system includes a terminal device, and a content distribution server connectable to the terminal device. The content distribution server includes a capability information obtaining unit to obtain capability information of the terminal device that requests a target content; an element extraction unit to obtain the requested target content and to extract a sub-content element composing the target content; a comparison unit to identify a sub-content element that can be used at the terminal device based on the capability information, and to compare the identified sub-content element based on the capability information and the extracted sub-content element to determine which sub-content element can be used at the terminal device; an output determination unit to determine whether separation of the target content is required to distribute the sub-content element to the terminal device; and a separating unit to separate the target content into sub-content element if separation is required.

1. A content distribution system, comprising:
a terminal device; and a content distribution server connectable to the terminal device via a network, the content distribution server including circuitry configured to
obtain capability information specifying one or more capabilities of the terminal device that requests use of a target content media file as a content-use request,obtain the requested target content media file from a content storage device and to extract a sub-content element composing the target content media file, the target content media file including a plurality of different types of sub-content elements corresponding to at least two types of media selectable from moving image, audio, still image, and text,a comparison unit to identify a sub-content element that can be used at the terminal device based on the capability information, and to compare the identified sub-content element based on the capability information and the extracted sub-content element to determine which sub-content element can be used at the terminal device,determine whether separation of the target content media file is required to distribute the sub-content element that can be used at the terminal device to the terminal device, andseparate the target content media file into each of the sub-content elements, which correspond to the at least two types of media selectable from the moving image, the audio, the still image, and the text, as a separated sub-content element, in response to determining that separation of the target content media file is required.
